1957 - Ultra-thin revolution

Faithful to its pioneering spirit, Piaget began to design and build the ultra-thin movements that were to become one of the company’s “signatures”, making an enduring impression on the watchmaking world. In 1957, the Manufacture introduced the famous ultra-thin hand-wound Calibre 9P, which was only 2 mm thick. In 1960, Piaget launched the Calibre 12P, the world’s thinnest self-winding movement. It measured just 2.3 mm thick.

This mastery of the infinitely small was not simply an expression of unusual technical ability. Thanks to their thinness and reduced size, these two mechanical calibres and their successors offered Piaget’s designers completely new perspectives by opening up the possibility of all sorts of bold creative ideas: ultra-thin profiles, generously sized dials, coin watches, shaped cases, etc. The Manufacture used all of these opportunities to its best advantage by developing a number of creations that were to leave their mark on the history of contemporary watchmaking.
